2 Claims.

This invention relates to mortar applying devices.

An object of this invention is to provide a device for applying at leasttwo parallel strips of mortar on a tile in one operation.

7 Another object of this invention is to provide a device of this kindwhich is initially dipped into a batch of mortar for picking up at leasttwo strips ofmortar which are applied to the tile in a single operation.

A further object of this invention is to provide in a mortar applyingdevice of this kind, means for holding the device in the desiredposition with respect to the tile so that the mortar may be applied tothe tile in an even depth and in uniform positions.

With the above and other objects in view, my invention consists in thearrangement, combination and details of construction disclosed in thedrawings and specification, and then more particularly pointed out inthe appended claims.

In the drawings,

Figure 1 is a detail plan view of a mortar applying device constructedaccording to an embodiment of this invention,

Figure 2 is a detail side elevation of the device,

Figure 3 is a sectional view taken on the line 33 of Figure l,

' Figure 4 is a fragmentary sectional view taken on the line 4-4 ofFigure 1.

Referring to the drawings, the numeral I ll designates generally a framestructure which is formed of a pair of end plates II and I2, havingupper flanges I3 and M respectively. The end plates have securedtherebetween a body plate I5 which is secured between the end plates byany suitable means, and the body plate I5 is formed at the oppositelengthwise edges thereof with upwardly offset truncated V-shapedchannels I6.

The channels it open downwardly and angle fastening means I'l aresecured to the opposite ends of the channels I6 and to the end plates.The body plate I5 is formed with at least a pair of upwardly extendingears I8 which may be secured by rivets or spot welding, as indicated atI9, to the inner sides of the end plates.

The end plates II and i2 are of like construction and each end plate isformed in the lower edge thereof with a truncated V-shaped cutout Alland the upper edge of the cutout is defined by an inwardly projectingflange ZI. The cutout 20 forms a pair of positioning legs 22 whereby theend plates may be properly positioned over the upper end of a tile T, asshown in Figure 3. The marginal edges of the end plates II and I2 arebraced by angled bracing flanges 23 and a foot flange 28 is formed atthe lower end of each leg 4 Each channel I5 is adapted to be normallyclosed by an elongated valve or gate 25. The valve or gate25 is formedby bending an elongated flat strip upon itself to form a V-shaped valvemember, as shown in Figure 3, and an elongated rod 26 extends betweenthe end plates II and I2, being formed with a head 27 at one end and acotter pin 23 is extended through the other end for holding the rod 26against endwise movement. In this manner the rod 2'! may be withdrawnfor either repairing a valve or taking the valve from the frame forcleaning thereof, Where the mortar or mud adheres to and dries on thevalve.

These two valves are pivoted at their outer lengthwise edges and areadapted to be swung downwardly to open position by downward movement ofpairs of valve operating rods 29. The rods 29 are extended at theirlower ends loosely through openings 30 formed in the inner small edgesofthe valves 25, and a lower cotter pin 3I is extended through the lowerrod 29 and is adapted to bear against a washer 32.

- The upper cotter pin or fastening-member 33 extends through the rod 29above the valve 25 and an upper washer 34 is interposed between thecotter pin 33 and the upper side of the valve 25. The rod 29 extendsloosely through the opening 35 formed in the body plate I5 and isconstantly urged upwardly to valve closing position by means of a spring36. The spring 36 at its lower end bears against a washer 3'! engagingon the upper side of the plate I5 and the upper end of the spring 36bears against an outwardly proiecting lug 38 carried by a depending arm39. The arm 39 forms one leg of a U-shaped support 40, and the lu 38 isformed with an opening 4| through which the upper end of the rod 29loosely engages.

- An upper cotter pin 42 is extended through the rod 29 and a washer 43is interposed between the cotter pin 42 and the upper side of the lug38. There are two of these U-shaped. members which are secured to thelower side of a movable handle or valve operator 44. The handle or valveoperator M is slidably mounted on a pair of upstanding rods 45 havingupper heads 46 and the rods or guide members 45 are secured by nuts 4!and it to the plate I5. The rods 45 are adapted to slidably engagethrough metal bushings 49 which are provided in the opposite endportions of the handle or operator 44.

In order to provide a means whereby the operstar 44 may be presseddownwardly, I have provided a lfixed handle 50 which is carried by a U-shaped support '51, being secured thereto by fastenin means 52. Theopposite dependin legs of the inverted U-shaped support 5| are formedwith outwardly extending flanges 53 which are secured beneath the uppernut 48 holding the guide bolts 45 on the plate IS. The U-shaped members40 are secured to the handle or operator 44 by means of 'a pair of boltsor fastening members 54.

In the use and operation of this device, the handle 44 is grasped in onehand and moved downwardly by also grasping the stationary handle 58.This downward movement of the handle or valve operator 44 will swing thetwo valve members 25 downwardly to open position. The frame is thereuponextended into the mortar or mud to a point where the material willengage within the channels IS.

The movable handle 64 is then released so that the valve members 25maybe swung upwardly to closed position, thereby trapping the mud ormortar in the chamber 55 formed by the channels I6. The frame is thendisposed over the top of the tile T, the ends I I and I2 having theflanges 2-1 engaging on the top of the tile. The downwardly .fiaredinner edges of the feet 22 provide a convenient means whereby the framewill be properly centered over the tile, and when the frame rests on topof the tile the movable handle '44 is depressed, forcing the valves 25to open position and permitting the mud or mortar to drop onto theopposite lengthwise edges of the .tile T.

Witha mortar or mud applying tool as hereinbefore described, a, uniformquantity of material is applied to the upperedges of the tile and wherethe tile is formed with transversely extending walls, such walls may besuitably coated with mortar by a trowel or the like. It will also beunderstood that this tool may include the transverse channels and valvessimilar to the lengthwise valves 25 for applying the mortar to thetransverse walls of the tile.

It is to be understood that the term tile as herein set forth "shallinclude bricks, hollow tile, terra cotta, concrete blocks or othermasonary surfaces.

I do not mean to confine myself to the exact details of constructionherein disclosed, but claim all variations falling within the purview ofthe appended claims.

What I claim is:

1. A mortar applying device comprising a frame formed of a horizontalplate and a pair of end plates depending from the ends of said firstplate, said horizontal plate being formed with a pair of elongatedparallel downwardly facing mortar receiving channels on said horizontalplate, a valve member for closing each channel at the open end thereof,means pivotally mounting said valve members below said horizontal plateat one side of said channels, a common operator for said valve memberscarried by said horizontal plate, each of said end plates being formedwith downwardly divergent tapered cutouts within which a :tile isadapted to engage .to thereby correctly position said channels relativeto the tile, and means normally urging said operator to hold said valvemembers in closed position whereby movement of said operator against thespring tension thereof will pivot said valves to open position fordepositing mortar on the tile.

.2. VA mortar applying device comprising a frame including a horizontalplate and a pair of depending vertical end plates, downwardly open-..ing channel members closed at the upper end thereof on said frame,valve members pivotally mounted on said frame for closing the open end.of said channels, and a common operator for said valve members, springmeans constantly urging said valve members to channel closing position,each of said end plates formed with a downwardly divergent recess forengaging over the upper end of a tile on which the mortar is to beapplied for positioning the frame on the tile.
